EOG Well Spacing

Oil and Gas Leasing Help

I have come across a few articles mentioning EOG Resources' plans to utilize 40 acre horizontal well spacing. Assuming a 400 acre pooled unit, does this mean that EOG could conceivably place ten wells within the unit. Any response is greatly

Regards,

Mark, you might post which county and state you're referring to.

I know EOG has discussed trying smaller spacing units in North Dakota. Though their existing ones are typically 640 acres or 1,280 acre units. I'm not aware of any 400 acre units there.

I saw some sweet 1/4 section horizontal wells drilled by SM Energy in ND, with production only slightly less than 5,000 and 10,000 foot lateral wells surrounding them, which adds another datum to the concept that an XXL lateral well may not be best in an area without great field pressure, but they sure hold alot of territory.

Thanks for your reply. The pooled unit is in Karnes County, Texas and has 335.44 acres with one horizontal just permitted. Its the smallest unit I have seen to date. With today's technology, how many wells could a unit this size handle?

Thanks.

Mark, I'm not familiar with the activity down in your area so I can't say for sure. However, I would think your guess is about right... 40 acre spacing should ultimately result in ten wells on 400 acres, etc... (assuming the entire area is deemed to have production potential).

As Mr Kennedy points out, much of the spacing up in the Williston Basin (MT & ND) has been dictated by holding by production the largest possible amount of acres with a single well. Now that the HBP process has largely been completed up here we may see smaller spacing as the in fill drilling continues.

Thanks for your response. I noticed that a recent federal reassessment of oil-and-gas resources in North Dakota by the EPA found the state holds twice as much shale oil — and three times as much gas — than was previously estimated.

Mark, 40 acre spacing in Karnes County is very aggresive for horizontals. I would not count on this at all.

Thanks for the response. I had the same thoughts but I wanted to check with the Forum.

Thanks again.
